600 RS Engine • New ECU Mapping • New Dual Air Intake System • New Tuned Pipe Support • New stronger motor mounts • Runs on 98E octane fuel
600 RS Engine • We recommend using a good quality 98E octane fuel • Peak Torque @ 8100 RPM • Peak HP @ 8300 which builds to 8500 with hot pipe
600 RS Engine • Technical Data • Piston to cylinder clearance • -.004 + or -.0005 • Piston Ring end gap • -min. .016-.021 • -max. .028-.033 • Replace base gasket with exact size only, same as original
600 RS Engine Pipe Heat Function • On dash display, select EGT • Depress holeshot button, slowly depress throttle, build to approx 5000 RPM, avoid backfire from too much throttle

2009 Rev-XP 600RSCarburetor Synchronization&TPS adjustment procedure Ref pg 47
Tools Required • 10mm open end wrench • Phillips Screwdriver • Small mirror • Small Flashlight • Supply Harness – Part # 529035869 (7-19) • 12v Cable Supply – Part # 529035997 (7-20) • 12 volt battery
Carburetor Synchronization • Remove the airbox. • Place a mirror so you can see both carb slides. • Check the throttle cable tension at the throttle lever (slack should be at a minimum). • Press the throttle lever to WOT. • Look at the carb slides to see if they are equal in height and clear the bore of the carbs. Adjust the throttle cables if they do not. • Check the throttle cable tension again at idle position (minimum slack). • Slowly open the throttle and watch to see if both carb slides rise at the same time.
Carburetor Synchronization • Adjust the idle screw so both carb slides open at the same time. • Again, check the throttle cable slack at the idle position. Must be minimum slack in the cable. • Tighten the cable jam nuts and recheck the carb slide operation. • Re-install the airbox. • Your carb slides are now synchronized
TPS Adjustment • Using the electrical supply harnesses and the 12v battery, connect to the diagnostic port on the vehicle. • The instrument cluster will light up. • After the “wake-up” of the dashboard, push and hold the throttle lever to W.O.T. position. • Press on the “Holeshot” button, hold it for 5 sec.
TPS Adjustment The check engine light will appear when the TPS adjustment is complete. Release the throttle lever and the “Holeshot” button. Disconnect the battery and the supply harness. Put back the diagnostic port in its connector on the vehicle.

Clutching Understanding basics, crucial for tuning • Driver input-Data acquisition very important • Know and tune to peak TORQUE RPM and peak HP RPM • Testing - learn what changes to make for track, conditions, temperature, elevation, air density • Knowledge of these factors and cumulative efforts on your part will make the winning difference
Clutching Tools Needed • Drive clutch puller # 529 022 400 • Button retainer forks # 529 005 500 • Drive pulley retainer # 529 035 674 • Spring compressor # 930001
600 RS Tuning Components Lightweight TRA III Drive Clutch • TRAIII Adjustments • Drive Spring • Ramp • Pin Weight • Calibration Screw( Clickers) Team Performance LW Driven clutch • Team Performance Adjustments • Driven Spring • Helix • Belt Deflection
Drive Spring Controls Engagement RPM well as shift RPM • TRA springs measured @74mm (2.9 in.)-41mm (1.6 in) Read with stripes down • Large assort of springs available
TRA Drive Springs Ref pg 139
Ramp • The profile of the ramp controls the axial or shift force generated to the drive belt • It is the angle of the ramp at the point of roller contact that determines the shift force • BRP has a wide variety of ramp profiles available
Ramp Characteristics Ref pg 129
Roller Pin Weight • Shift force directly controlled with weight of pin • Lighter pin weight-Higher RPM • Slower upshift • Heavier pin weight-Lower RPM • Faster upshift
Calibration Screws(Clickers) • BRP only manufacture to offer quick external shift RPM adjustment • Cam adjuster allows you to raise or lower ramp, changing profile • Clicking up to higher # will slow upshift and raise RPM • Clicking down to a lower # will upshift faster and lower RPM
